Yang, can you share an update? Is the GYP-to-GN bridge available? Is real GYP still supported in specific V8 versions?
We were able to build the 6.4 branch tip on Windows using our existing GYP-based script with Visual Studio 2017. Do you know whether that's likely to continue working in 6.5 and beyond?
